CEREC Restorations are the latest form of porcelain restorations being made by utilizing a new technology called CAD-CAM (Computerized Assisted Design- Computerized Assisted Milled).
The procedure is as follows:
The tooth is prepared, removing all decay and an impression is taken. If the conventional impression is taken it will be poured into stone and than either imaged directly or have a small coating of the titanium dust to help with the imaging. The imaging is optical and uses an infrared wavelength. This image is converted to a format that the computer understands and an image appears on the TV-screen for the dentist to use in designing the restoration. After the design has been approved the computer information is sent to the milling (Cutting) station which will sculpt the restorative material to fit the design (Tooth and Bite).
After the restoration is checked for fit, color and harmony with the tooth and body, the restorative material (as is the tooth) is then prepared to the manufacturer’s specification (acid etched, silaned, Bonded, etc.) to be made “sticky” to the cement being used. The Cerec restoration is then permanently joined to the tooth. This is all accomplished within one appointment from start to finish and all within the dental office. You can leave with your crown that same day!
